Polystore

多态数据存储

// It's a HashMap<K = i32> storing polymorphic values:
let mut store = HashMap::new();

// k1 is the key 1 tagged with the element type `&'static str`
let k1 = store.insert(1, "A static str");
if let Some(v) = store.get_mut(&k1) {
    *v = "another str";
}
assert_eq!(store.get_tagged(&k1), Some(&"another str"));

// untagged keys work too (relying on type inference, here `String`):
store.insert(2, "A String".to_string());
assert_eq!(store.get(&2), Some(&"A String".to_string()));

assert!(store.contains_key(&k1));
assert!(store.contains_key(&1));
assert!(!store.contains_key(&3));
